MILK RECEPTj-LCLE FOR CENTBIFUGAL SEPARATURS.

Application filed August 21,1913. Serial No. 785,923.

Specification of Letters Patent.

Patented Sept..29, 1914.

To all whom it may concern i Be it known that we, CARL ALRIK HULT, a subject of the King of Sweden, and resident of Inedalsgatan 1, Stockholm, in the Kingdom of Sweden, and KNUT AnoN' .liMANUEL TINNBERG, a subject of the King of Sweden, and resident of Partille, in the Kmgdom of Sweden, have invented certam new and useful Improvements in. Milk-Re ceptacles for Centrifugal Separators, of

which the following is a specification, refso arranged, that it can be used as rotating or oscillating churn i. 6. form the rotating or oscillating vessel of a churn. By means of a receptacle thus arranged the advan tage is gained that one vessel can beused for the same purposes, for which hitherto two vessels always have been used, which vessels seldom are used simultaneously but involve double expense when bought, transported and so on. For the gaining of the said purpose the receptacle, in order to be used as a churn, is suitably contracted (or has a neck) at its top end for the retaining of the contents during the rotary motion of the receptacle, and is provided preferably at its bottom with a device, by means of which the receptacle can easily be connected with the driving mechanism of the churn and disengaged from the same. A ring shaped cover may be substituted for the said contracted shape which cover fits tightly to the top edge of the receptacle and prevents the cream from being thrown out during the churning operation. The said contracted shape and the said cover may, evidently, be used simultaneously.

The means, used for connecting the receptacle with the driving mechanism of the churn, may be constructed in different ways. For the said connection the ordinary opening provided in the bottom of the receptacle and shut by a cock or the like may,

for instance, be used, in which opening, after the removing o the plug, a suitable part is located, which is brought into screw threaded engagement with the driving part or the shaft.

For the supporting of the receptacle and dish, a flange,

the centering of the salne with. relation to the driving shaft, which is vertical, a wide like provided at the, top end of the shaft may be used, the bottom part of the receptacle being so shaped, that the receptacle can be placed on the said disk etc., as on a stand, and embraces the said disk, flange a cross shaped partor the etc. to a greater or less extent or vice versa.

Many other means may, however, be used for the said centering, for instance a sleeve and a pin or the like. The means connecting the receptacle with the shaft may, furthermore, be arranged like a so called. bayonet-clutch, the desired easy connection and disengaging being thereby rendered possible. The said bayonet-clutch may consist of pins,

cars or the like, provided on one of the h parts '(the bottom of the receptacle or the shaft) and of corresponding slots, angular projections or the like provided on the other part. By rotating the receptacle with relation to the shaftv the former is easily connected with the latter or disengaged from the same. The clutch may be modified in many ways or other connecting means may be used, andthe receptacle and the shaft may be connected either directly or indirectly by means. of a part, which is rotatable by itself, so that the receptacle need not be rotated ln order to secure that the cream is rotated with the receptacle when used as a churn vessel, the receptacle is provided inside with wings or the like.

In the accompanying drawings Figure 1 shows in a vertical section the receptacle mounted on the driving shaft ofa churn.

Fig. Qshows in a vertical section the receptacle and another device connecting the re ceptacle with the shaft of the churn. Figs. 3 and 4 show in a vertical section and in a plan view respectively the receptacle and the shaft of the churn connected directly by a bayon'etclutch. Figs. 5 to 7 inclusive show modificationsv of the said clutch. Figs. 8 and9 show in a vertical section and in a plan view respectively a bayonet-clutch having a special rotatable part for the con necting of the receptacle and the shaft.

Fig. 10 shows in a verticalsection a modi fication of the clutch last mentioned. As seen from the drawings, the receptacle has a shape suitable for its use as a rotating churn vessel, the side wall being bent outward and the top opening being la gecover 2, Fig. l, fits tightly in the said opening. Besides, the churn comprises the frame 8, the verticalshaft l, on which therecep- 'tacle 'is mounted, the driving shaft 5, the gearing 6 and the crank 7, which parts may bearranged in the ordinary manner or as shown in the drawings, or in any other manner, if necessary. in order that the receptacle 1 may easily be mounted on the shaft 4, the latter is provided at its top end with a horizontal cup-shaped disk 8, having a vertical flange, and the receptacle is so "shaped at its bottom, that it can be placed on the said disln The receptacle is provided at its bottom with a flange 9, projections or the like, which fit to the said flange of the disk, inside or outside the same. Owing to the said arrangement the receptacle will have a fixed position on the shaft, co-axially to the same. The receptacle is provided at the center of the bottom with the ordinary cock for the admitting of the milk to the centrifugal apparatus, when the receptacle is used as a milk reservoir in the said apparatus. As the receptacle is to be used as a churn vessel, a tap i1 is mounted on the seat of the plug which is removed. The

said tap 11 fits tightly to the said seat and is screw threaded, so that it can be brought into engagement with the top end of the shaft 4; or with the said disk 8, which is provided with a corresponding screwthreaded opening. By the said means the receptacle 1 is connected with the shaft and is compelled to partake in its rotary motion.

' The plug may also be so arranged, that it milk flowing downward into the centrifugal apparatus. To the frame 3 an upright 12 is fixed, to which the so called agitator 13 is. fixed by means of an arm.

' 33 are the wings mentioned above, which wings are provided in the receptacle 1 and cause the cream to partake in the rotary motion of the receptacle, when it is used as a churn vessel. The said wings are preferably provided at the bottom of the vessel but may have 'anyother suitable position. The number of the wings is arbitrary. EX- perience has proved that the wings need not be large for the purpose just mentioned and for that reason the wings form no obstacle worth mentioning in the receptacle when it is used in the centrifugal apparatus or while it is cleaned. The wings may be fixed in the receptacle in a detachable manner, if wanted.

in Fig. 2 the seat of the cock consists of a central tube l l provided. in the receptacle and extending upward. A shaft 15, fixed to the frame, extends through the said tube and for distance aluu'e the top end of the tube. In the top end of the shaft 15 a groove 16 is provided. he arm 18 of the stationary agitator 1? is formed to or pro vided with a sleeve 19, which is slid on the shaft 15 and provided with a pin 20 which engages the said groove 10. The said sleeve :fi 'n or on the tube and forms a bearing for the top end of the same. The gearing actuates the disk 8, which in this case rotates around the stationary shaft 1 The receptacle is held in its place on the disk by the gravity. In order that the receptacle iiuay be positively actuated by the disk, it may be provided with a projection 21 or the like, which engages a recess provided in the disk 8. On the tube a ring or sleeve 22 is slid, closing the holes provided in the lower end of the tube, which holes should be open, the receptacle is used in the centrifugal apparatus, in which case the ordinary plug provided in the tube. [is the receptacle 's to be used in the centrifugal apparatus, it s taken off the shaft, the plug of the cock s located in the tube, the receptacle is mounted on the centrifugal apparatus, the milk filled in and the cock opened.

The shape of the receptacle and the manner in which the receptacle is applied to the driving mechanism of the churn may evidently be modified in many ways. For instance arms extending from the shaft may be substituted for the disk 8, which arms are provided with openings for corresponding pins provided in the bottom of the receptacle and so on. The cock, provided in the bottom of the receptacle, may be arranged in many other manners than shown in the drawings. Also in the form of the invention shown in Figs. 3 and i; the receptacle 1 is carried by the cup shaped disk 8 provided on the top end of the driving shaft i. The flange 9 of the receptacle has an inward extending rib 23 which is engaged by hooks 24L fixed to the flange of the disk 8. notches are provided in the rib 2o, through which the said hooks Qt pass, as the re ceptacle is being mounted on the disk 8. As the receptacle is then turned with relation to the shaft, the hooks 2% engage the top side of the rib 23 and positively connect the receptacle with the driving shaft. A suitable abutment (not shown) may be provided for limiting the said turning of the receptacle and a jam screw (not shown) or the like may be provided which when tightened prevents the receptaclegfrom being turned I in the opposite direction. y The parts ofthetop side of the rib 23,

which are engaged by the hooks, may be somewhat inclined, in order that the receptacle may be forced against, the supporting disk, as itis turned with relation to vessel. By turningthe receptacle in oppo-' site direction the receptacle is easily brought out of engagement with the shaft. The agitator 13 mentioned above and the means carrying the same are not shown in Fig. 3..

Instead of the said hooks a flange 25 may be provided in the cup shaped disk 8, in which flange notches are provided. The rib 23 has a corresponding shape and notches, as shown in Fig. 5, which figure is easily understood without further explanation. As shown in Fig. 6 the hooks 24 are fixed to the receptacle 1 and engage a flange 26, similar to the flange 23 and provided on the outer side of the cup shaped disk 8. As shown in Fig. 7 pins 27 with heads are located at the bottom of the receptacle and slots 28 of the shown shape provided in the flange of the disk for the said pins. Also in the receptacle shown in Fig. 3 the bottom cook 11 mentioned above is provided. Instead of a solid disk or cup 8 a cross shaped piece or the like provided on the shaft may be used.

In the form of the invention shown in,

Figs. 8 to 10 inclusive a disk 29 or the like is located on the bottom of the cup shaped disk, which disk 29 can be rotated around a pin 30, connecting the disk 29 with the shaft 4. The said disk 29, for which a cross shaped piece or the like may be substituted, is provided at its outer edge with hooks 31, which engage the flange 23, projections or the like, provided on the receptacle 1. The cup shaped disk has an opening for a handle 32, which is slid into a recess provided in the disk 29 and by means of which the disk 29 can be rotated. Consequently, the connecting of the receptacle with the shaft is effected in this form of the invention indirectly by rotating the disk 29. The clutch is, however, of the same type as that shown in Figs. 3 to 7 inclusive, viz. a bayonetclutch. The receptacle may be forced against the cup shaped disk by the pin 30, which is in screw-threaded engagement with the disk and has a nut or head, being rotated together with the disk 29 and thus moved farther downward into the disk (Fig. 8), as the disk 29 is rotated in one direction for the fastening of the receptacle. The pin is raised when rotated in the opposite direction. he gained by the disk 29 being in screw threaded engagement with the pin, which The same object may then is stationary, Fig. 10, or by slanting surfaceson the flange 23. or thelike.
